The purpose of this paper is to compare the cognitive styles of trainee teachers with their notions of differentiation and perceptions of its place/location within their teaching and learning during a PGCE programme of ITE.

A total of 80 trainee teachers completed the Cognitive Style Index (CSI) at the beginning and at the end of their course. After completing the CSI measure trainees received instruction on cognitive styles. To assess their initial understanding and prior knowledge of differentiation, all trainees completed a questionnaire at the beginning and at the end of their course.

At the outset rudimentary understandings of differentiation were found to be held by the trainees, as well as stylistic differences between the four style groupings. Gains in understanding of differentiation and the use of cognitive style in school were evident in all trainees. Moderate changes in style were evident, with all trainees becoming more intuitive over the course of the programme.

The sample size may be seen as a limitation in terms of generalisability.

The predominant direction of cognitive style movement was from analytic to intuitive. The suggestion that cognitive style, while relatively fixed, is also something that can be developed is a feature which should offer encouragement to those developing university courses through interventions such as this.

Teaching sessions on how cognitive styles can be used in the classroom were used to enhance trainee understandings of individual learning differences and increase awareness of one's own style to facilitate understanding of differentiation.

MicroCheck is provided by the vendor, a company that sells books, library supplies and automated services to libraries, as part of a catalog conversion service that company offers. That is, converting catalog records to machine‐readable form. The vendor maintains computer‐stored cataloging records. During the conversion process these are matched against the customer library's own cataloging records. The price of the conversion process is based on the number of matches anticipated between these two sets of records.

Food safety is now big news. As a result of all the recent media publicity, there has been a growth in consumer concern about possible hazards linked to specific foods. Individual products and product ranges can suddenly find themselves highlighted in newspaper articles and in radio and television programmes. This can cause an immediate fall in sales so that large quantities of food have to be destroyed. Inevitably, this has an adverse effect on the profitability of the producers. Factories have been closed down with a consequent loss in jobs and company profits have fallen.

When INFROSS began in the autumn of 1967, although a large number of studies had been conducted into the requirements of scientists for information, very little had been done in the field of social science information. There are a number of possible reasons for this. Social scientists, faced with a much smaller total volume of information, were much less information‐conscious and less inclined to seek for solutions. There are very few specialist libraries in the social sciences, and few librarians were therefore confronted with social scientists' information needs in the same way as librarians in scientific libraries were confronted with users and their problems. Finally, until OSTI came along there was little in the way of funds to support this kind of research. This almost total absence of previous research had its disadvantages and advantages. There were very few clues to guide us, and we were therefore working to a certain extent in the dark. On the other hand, we had a clean and open field uncorrupted by confusing and non‐comparable studies. There is something to be said for being one of the first in a field.

The U.S. Congress has been struggling to create a comprehensive energy program. A key component of the present attempt, recommended by President Carter, is a synthetic fuel program. In July of 1979, the President asked for an $88 billion “crash program” to encourage development of synthetic fuels. To date, a three month struggle to reach a consensus between House and Senate conferees has brought only limited results. Compromise is emerging in the form of a proposal for a “synthetic fuels corporation.” The body would have the authority to disperse $20 billion in the form of federal loan guarantees and purchase agreements with more money to become available later.

Wolverhampton based Ferro (Great Britain) Ltd has acquired Macpherson Drynamels Ltd—one of Europe's largest powder coating manufacturing facilities — in a multi‐million pound, unspecified, deal.

Although many companies have become financially weak in the current economy, Blue Diamond Growers, a worldwide producer and marketer of almonds, and Harley‐Davidson, Inc., are thriving. While other companies are cutting back on production and staffing in order to maintain a financial foothold, Blue Diamond and Harley‐Davidson remain strong in their respective industries: Blue Diamond processes and packages one‐third of the world's almond crop each year, and Harley‐Davidson has cornered 60% of the market for heavyweight motorcycles.

Distributions of index terms have been used in modelling information retrieval systems and databases. Most previous models used some form of the Zipf distribution. This work uses a probability model of the occurrence of index terms to derive discrete distributions which are mixtures of Poisson and negative binomial distributions. These distributions, the generalised inverse Gaussian‐Poisson and the Generalised Waring give better fits than the simpler Zipf distribution, particularly in the tails of the distribution where the high frequency terms are found. They have the advantage of being more explanatory and can incorporate a time parameter if necessary.
